Fensport GR Yaris - 2025
2025 Javelin Sprint Series and Toyota Sprint Series - Overall Champion
Adrian: What a year, after missing the first round due to family commitments, it meant we had to have reliabilty and perform well on the remaining rounds. Everything went to plan with 6 wins from 6 starts to secure both the Javelin and Toyota Sprint championships.
The 2025 GR Yaris was transformed by the small adjustments we had made, the car was 20kgs lighter, the rear differential is now limited to 60% rear bias which has definitely helped in getting on the power much earlier. The other big change was the switch to Extreme tyres, the mechanical grip is transformed with corner G force now averaging 1.6g. All the above helped me to set personal best times at all the circuits, some were over 2s faster than ever before.
A huge thank you to Ollie, Michael, Tom and Andy who all helped to fine tune the car, its a fantastic little beast to drive :)
Congratulations to Dimitrij Sribnyl in his 4wd BRZ (below left) on 2nd place and also to Callum Holme (below right) in 3rd overall in his rapid impreza :)
A huge thank you to all of our team, sponsors and supporters for all your help in 2025 :)
